Abstract

A method for reducing power consumption in a mobile station is provided. The method includes holding data associated with a first polling message until a first scheduled RF wake-up of the mobile station. The method also includes sending the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station. The method further includes holding a second polling message until a second scheduled RF wake-up of the mobile station. The scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network. In certain embodiments, the polling messages are associated with an ActiveSync® Ping command.

Claims

1. For use in a wireless communication network, a mobile station configured to reduce power consumption, the mobile station comprising:

a battery; and

a controller operatively coupled to the battery, the controller configured to;

hold data associated with a first polling message until a first scheduled RF wake-up of the mobile station;

send the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;

hold a second polling message until a second scheduled RF wake-up of the mobile station.

2. The mobile station of claim 1, wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.

3. The mobile station of claim 1, the controller further configured to establish a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.

4. The mobile station of claim 1, wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.

5. The mobile station of claim 1, the controller further configured to turn off a transceiver of the mobile station during an idle period between the first and second scheduled RF wake-ups of the mobile station.

6. The mobile station of claim 1, wherein the first and second polling messages are associated with an ActiveSync®

Ping command.

7. The mobile station of claim 1, the controller further configured to:

start a timer; and

send data associated with a third polling message before a third scheduled RF wake-up when the timer reaches a predetermined value.

8. The mobile station of claim 3, wherein the controller is configured to establish the TCP connection by placing the mobile station in a Cell DCH state.

9. For use in a mobile station in a wireless communication network, a controller configured to reduce power consumption by the mobile station, the controller configured to:

hold data associated with a first polling message until a first scheduled RF wake-up of the mobile station;

send the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;

hold a second polling message until a second scheduled RF wake-up of the mobile station.

10. The controller of claim 9, wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.

11. The controller of claim 9, the controller further configured to establish a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.

12. The controller of claim 9, wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.

13. The controller of claim 9, the controller further configured to turn off a transceiver of the mobile station during an idle period between the first and second scheduled RF wake-ups of the mobile station.

14. The controller of claim 9, wherein the first and second polling messages are associated with an ActiveSync®

Ping command.

15. The controller of claim 9, the controller further configured to:

start a timer; and

send data associated with a third polling message before a third scheduled RF wake-up when the timer reaches a predetermined value.

16. The controller of claim 11, wherein the controller is configured to establish the TCP connection by placing the mobile station in a Cell DCH state.

17. For use in a wireless communication network, a method for reducing power consumption in a mobile station, the method comprising the steps of:

holding data associated with a first polling message until a first scheduled RF wake-up of the mobile station;

sending the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;

holding a second polling message until a second scheduled RF wake-up of the mobile station.

18. The method of claim 17, wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.

19. The method of claim 17, further comprising:

establishing a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.

20. The method of claim 17, wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.
